I am a bit confuse with a question from a home work that I need to do by today please help!
HW question...
1) A sample of neon gas occupies 8.77 L at 20°C. What is the pressure, in atmospheres, exerted by 1.45 mol of this gas?
When you've gotten the answer to this question you will then round to the hundredths place.

DrBob222,
PV = nRT
P in atmospheres, V in liters, n is mols (mols = grams/molar mass), R is general gas constant (I assume you know that), and T is temperature in Kelvin (Celsius + 273 = Kelvin).
Post your work if you need more help.
